I’m very familiar with airborne spectra gathered over the maralinga area and have often joked about the existence af “Maralingaite” as a pun on trinitite. After the post I will chase our geologists and see if the...

Re: Menzenschwand, Germany

Hi guys Abilene could be correct. The black mineral is possibly uraninite / pitchblende or davidite. The yellow green flakes could be autunite - which Fluoresces a bright green with SW MW and LW ultraviolet lights. It could also be torbenite - or metatorbenite. This mineral doesn’t fluoresce and is ...

Re: The Most Radioactive Room in My House

Hi Massimo

I know my calibration was a bit off, I used only a quick Cs
Source. I plan to run it again in the next few days but do a better calibration with either a thorium mantle or a radium card.

Thanks for your comments, much appreciated,

Cheers and regards
Gary

Re: The Most Radioactive Room in My House

I have read with interest this post from Go-Figure, so decided to run a preliminary experiment of my own. The results are shown below, and the next step is to enhance the lower energy levels. As a background, our house was built in the 1980's above the Willunga Slate quarry in South Australia. The b...

Puzzling N.O.R.M. Spectra

Greetings all, I have recently collected a few spectra of N.O.R.M specimens collected within South Australia. Some of the results are for me very puzzling so I have posted them with the hope that somebody can provide an answer. Firstly, the spectra were collected using a Bicron NaI probe, a GS-1100 ...

USB external sound cards

Hi All, If anyone is like me and is struggling with a Windows Surface pro with no line in jack, or a laptop with one input jack which double as either a microphone or headphone, of like me, you have one of each. Then an external USB soundcard is the way to go. If you require a cheap but reliable dev...
